Economical Solvent Distillation With Solvent Recycling Equipment
Being an environmental friendly company is an advantage, but maintaining this kind of reputation while saving money definitely does go a long way. Due to the growing use of chemicals in order to make different products, or cleaning products, more and more companies across the globe are using solvents.This in turn means that more money needs to be spent on disposing of these solvents in a safe environment. This job is done effectively by using a solvent recycler. However, nowadays, there are much more cost efficient ways of safely disposing of solvents. This is achieved by using an on-site solvent recycler. In fact, many vendors that sell solvent recyclers are able to ensure that you have the right type of system for your business.
One particular type of industry that relies heavily on using a solvent recycler is the automotive re-furnishing shops. The reason for this is because these shops utilize large amounts of paint thinner and solvent in order to clean their spray guns. Because of this, the combination of both solvent and paint waste creates a huge amount of waste stream for the shop. One way in which they might handle this is by using an off-site recycling facility. In order to achieve this, this waste would need to be shipped by using other means of transportation, which is usually achieved by using a waste hauler. Once the waste reaches these off-site recycling facilities, the solvent is then distilled, which in turn separates it and reclaims the solvent from the actual paint waste.These automotive refinishing shops are now also able to achieve this with less expenses attached to the bill. They are able to do this by using an on-site recycling system. It is this recycling system that is known as a an on-site solvent recycler. These recyclers are able to reduce the costs up to as much as 80% compared to the services that are charged in order to move the waste to an off-site facility. The best part is that these recyclers are able to do a very good job at keeping these shops environmentally friendly.
As for the “Go Green” matter, recycling your own solvent gives many advantages for your business. First, your company will be labeled as one of those companies that support the “Go Green” campaign, which is promoted globally. If your company is recycling its solvent, you are contributing to the well-being of our environment, which may eventually encourage other companies to do business with you. Starbucks and Wal-Mart are among some of the companies who have taken advantage of the whole “going green” movement. Even if you are involved in the B2B community, most companies prefer to do business with companies that have a good reputation of being environmentally friendly.
Distillation is a simple process that is being used by a lot of small and large companies today in order to reduce their waste streams and recover some of the reusable products. This in turn helps to keep their costs low considerably. Due to this process, recycling solvents has developed over the past 20 years with the use of batch stills. Using a solvent recycler equipment is the most important unit that is needed to recycle solvents, and has evolved considerably over the years to be more efficient, cost effective, and more importantly, to be eco-friendly. Solvent recycling equipment can come in sizes that usually range from two gallons per batch, to handling up to 100 gallons per batch, which in the end really does depend on the industry that uses these systems. In fact, because recycling equipment has become more and more effective while at the same time remaining inexpensive, a growing number of companies are now beginning to rely on these systems as a way of replacing third-party companies that usually do the recycling for them. There are even systems that are able to do the whole process without any extra manpower needed, while still being able to ensure that the process is completed successfully. In fact, while these units cost several thousand dollars, what may seem expensive at first can easily pay itself off after a year or two. In certain process industries, nearly all equipment vendors will suggest that companies who utilize them should purchase solvent recycling equipments, simply because they can help to lower the cost of the very expensive solvents that are required in their equipments. There are three principal components in any solvent recycling equipment that is very important. The first component is a tank in which the waste will be deposited. The second principle is a heating system, which is used to turn the liquid part of the waste into vapor. The third principal is a condenser. The condenser is used for cooling the vapor back into its liquid state.
The size of the solvent recycler will be determined by the size of the tank inside it. The different methods of heating includes, direct heat with the use of a heat plate or electric heating element, and indirect heat, where the oil bath that is surrounding the tank will be heated with direct electric heat and steam. Of all these methods, the most preferred approach is indirect heat because the heating is more uniform compared to the other methods. Solvent recycling equipment is unique among the other tools in the industry because they already do almost all of the work on their own. It is very important to use these units because of the increasing concerns for protecting the environment.
There are many manufacturing industries that produce these types of waste solvents. A basic list of these manufacturers can include Polymerization processes, metallurgical operations, surface coating, solvent refining, extraction of vegetable oil, cleaning operations and pharmaceutical manufacturers. The amount of solvent that is recovered from waste differs from about 40 to 99 percent. It usually depends on the recovery process that is employed in the solvent recycling, as well as the degree and characterization of the contamination.
You will discover three different processes of solvent recycling.The foremost is called solvent storage. Within this process, solvents will likely be stored before and after the recycling process. It will be stored in containers ranging from .2 cubic meters, which are roughly 44 gallon drums, to tanks that have a capacity of 75 cubic meters or more. Different sizes and types of tanks are used for solvent storage, and most of these have a fixed-roof design. There are two different types of emissions that come from fixed-roof tanks: these are known as working and breathing losses. A working loss is the combined loss from tanks that have been emptied and filled. A breathing loss is the removal of vapor from a tank through contraction and expansion. It will result in a change in barometric pressure and ambient temperature.
The second process is known as initial treatment. In this process, the waste solvents are treated through means of mechanical separation or through vapor recovery. In mechanical separation, the solid contaminants that are not dissolved will be removed from liquid solvents. Vapor recovery involves the elimination of solvent vapors from a gas stream to prepare for further reclaiming operations. The collection methods that are used include adsorption, absorption and condensation. The technical feasibility of the method is affected by different factors such as vapor composition and concentration, reactivity, solubility and the miscibility of the solvent. The condensation process in solvent recycling is done with the use of refrigeration units and water-cooled condensers. There is a big possibility that there will be explosive mixtures of a flammable solvent in the air during the gas stream process, so the air is therefore replaced with inert gas, like nitrogen. Any of the solvent vapors that was able to escape the process of condensation are then recovered by using absorption or adsorption.
Activated carbon adsorption is used to capture solvent vapors that escape during the process of condensation. These systems can capture solvent vapors that are below 4 cubic meters of air. Solvent vapors are absorbed by passing a stream of waste gas to spray chambers or scrubbing towers. This in turn will create a solvent and oil mixture. The third type of process is known as distillation and purification. In this process, after the initial treatment is done, waste solvents will be distilled to separate solvent mixtures and to eliminate all of the dissolved impurities in the waste solvent. Dissolved impurities are separated through the process of simple continuous or steam distillation, or by means of a simple batch. Solvent mixtures that are mixed together can be separated through simple distillation methods such as continuous rectification or batch rectification.
One way in which these small shops are able to effectively recycle solvents is by using an on-site solvent recycler. These systems are able to do the same type of job, except the costs will be substantially lower. By using these low cost on-site recyclers, it allows more companies to get involved, thus allowing the eco-friendly environment to grow more rapidly.
